RIP Maggie!
Not only the Harry Potter films, but a whole slew of other TV shows and movies that benefited from her wry wit and arch comments: Downton Abbey, Sister Act, A Room with a View, the First Wives Club, etc. (I always loved the more youthful Maggie's turn in
Death on the Nile (1978) as Miss Bowers, opposite Peter Ustinov as Hercule Poirot, and later in
Evil Under the Sun (1982) as Daphne Castle, and Peter Ustinov reprising his Poirot role. A good cast too: Roddy McDowall, Diana Rigg, James Mason).
So it seems that only Dame Judi Dench is now left to rule the roast. (I understand Maggie and Judi had a bit of a cheeky rivalry).
